I should have mentioned that i am using a gyro on the ailerons because my Typhoon rapidly rocks from side to side quite a lot - very highly swept models and deltas can be prone to it. It just looks poor, and fitting a gyro stopped that and makes it look "real" again as it flies level instead of rocking. It has also, as a side benefit, much improved the handling since rolls now stop dead and lock into level flight again, and steep turns have become smooth because when it rocked from side to side in a turn with a lot of up elevator, the bank angle was increasing and decreasing so it would climb and dive as the bank angle wobbled.

I would not hesitate to use a gyro again but the thought of it failing and causing loss of control has occurred to me, in future I will be getting the ones built into the Weatronic receiver system that I use.
